Asking for account while payment pending.

I have discussed with this seller and showed them a DC Universe Online account on stream via discord. We had agreed on a price and he stated he would like to pay via paysend, an app unfamiliar to me. As soon as he has paid he is begging for the account, despite me stating that I have not recieved any money. Furthermore, I have asked if payment status is "sending" which he confirmed. I asked that he wait till it says "sent" or there is a confirmation but he is not honoring my request, instead stating that I should give him the account to play. He has also stated that a middleman would ban me at this point, and threatened to report me to the police. Please see below the chain of our full conversation:
